When applying an oil, less is definitely more and better to apply several light coats than one heavy coat. Because if over-applied the drying time can be very slow and also feel tacky. A paint brush can over apply the oil and be the main cause of a problem so a rag can be a better tool to use. We would recommend a 1st coat diluted with White Spirit/Genuine Turps (30-50%) in most cases to help prime and help the oil soak in. Once dry, several thin coats is always a better option, being ready with the soaked cloth to remove any excess oil. When dry always wash out the rags well with detergent to avoid a the risk of spontaneous combustion.
